大型金融机构室内定位系统高效中间件的设计

金融机构内的重要区域对安全性及金融人员监管有较高的要求。由于室内环境复杂和所处理数据庞大等因素,室内定位系统在定位过程中会出现数据丢失和处理结果滞后的情况,导致安全性下降。本文设计的中间件通过初始化阶段预处理数据,在结合并行模式的线程池管理基础上,通过添加环形队列缓存池,达到了提高系统运行效率、减少数据丢包率和增强系统抗压能力的目的。中间件架构的可行性通过了实验验证。     

本科生导师制的优化研究:多学科交叉视角

本科生导师制往往由于受专业的限制,不能充分发挥作用.高校应当摒弃专业和学科限制,以兴趣导向、自由选择的方式建立跨学科的本科生导师制,提高导师指导效果,激发学生兴趣,提升学生综合素质.     

想拿世界冠军的重庆"阿甘"

——你是啥子? ——冠军. ——啥子冠军? ——世界冠军. 每当马俊才在训练中坚持不住的时候,教练姜舟就会向他喊话. 三级智力残疾的马俊才今年18岁,在重庆市特殊教育学校读高二,是校田径队400米跑种子选手,也是教练姜舟心目中"阿甘"式的人物,坚韧、执着、善良、热心. 起初,学校打算培养马俊才做失明长跑运动员的陪跑员.姜舟在训练时,要求队员围绕操场按照一分钟跑一圈的节奏跑,谁知马俊才一跑就跑了半个小时,若不是姜舟喊停,他还没有停下来的打算.从此,"阿甘"这个名字在重庆市特殊教育学校不胫而走.     

A systematic review of pharmacoeconomic guidelines

Objective: To review, summarize, and analyze both similarities and differences of pharmacoeconomic (PE) guidelines, to enable researchers to access their characteristics and the current state of PE guidelines; furthermore, to learn which methodological issues still remain contested and to promote the methodological development of PE guidelines.

Materials and methods: The authors performed a search for PE guidelines using PubMed, the Cochrane library database, and the websites of the International Society for Pharmacoeconomics and Outcomes Research. Information of each guideline was extracted using a pre-designed extraction template, which included 22 aspects; the guidelines were summarized in the forms of charts, and their characteristics have been described.

Results: A total of 40 PE guidelines were studied. The most common methodological issues include the types of analysis, sources for effectiveness, use of quality-adjusted life-years (QALYs) to measure outcomes, and use of incremental cost effectiveness ratios to present results. The majority of the guidelines preferred a cost utility analysis with outcomes expressed in terms of QALYs. Most of the guidelines preferred meta-analysis or meta-analysis of the randomized controlled trials, and required a systematic review of all evidence. Issues that varied most in the guidelines were the choice of the comparator, recommended costs to be included, methods related to indirect cost calculations, methods of sensitivity analysis, and discounting rate.

Conclusion: A comparison of these guidelines revealed that a number of differences exist among them in several key aspects, and some critical methodological issues still exist, for which no best solution is available. Furthermore, efforts need to be made to develop harmonious methods for the PE, and to improve the transferability of the outcomes of PE evaluations.     

海南岛休闲农业布局现状的实证分析

[目的]全面分析海南岛休闲农业布局现状,为海南岛休闲农业科学合理规划和均衡协调发展提供决策参考。[方法]文章利用海南岛259家休闲农业企业的地理数据,采用比较、缓冲、密度分析工具,从数量、类型、密度、距离衰减方面实证分析海南岛休闲农业的布局特征,并提出相应的优化对策。[结果](1)海南岛东部、中部和西部休闲农业数量分布比重分别为51%、29%和20%,其中国家级示范点数量分布比重分别为83%、17%和0%;(2)休闲农业主要类型有休闲农庄、观光农园、市民农园和农家乐,除休闲农庄在东部、中部、西部分布较均匀外,其他类型分布较不均衡;(3)距离市县中心越远,休闲农业分布密度越小,95%的休闲农业分布在距离市县中心30km以内,距离市县中心10~15km是休闲农业的高峰集聚区;(4)海南岛休闲农业已在海口、保亭、三亚、澄迈、琼中、琼海、定安、儋州形成8个高度集聚带。[结论]海南岛休闲农业无论在数量、类型和密度上都是东部地区最多,中部次之,西部最少。应积极推进具有农业发展优势的地区,因地制宜拓展产业休闲功能;休闲农业产品类型单一的地区,深度挖掘特色资源和文化内涵;加强休闲农业点与旅游景区、生活服务中心之间的跨区域联系,形成和谐发展的有机旅游整体,使休闲农业真正成为农业转型、农民增收的引擎。     

中部地区休闲农业可持续发展态势比较研究

[目的]通过分析中部6省休闲农业发展情况,对各省休闲农业可持续发展态势进行比较研究。[方法]围绕休闲农业可持续发展态势进行评价,根据休闲农业发展情况,确定休闲农业发展中的核心指标,从系统内部结构着手构建休闲农业可持续发展态势评价指标体系,并根据专家对各指标的打分结果,运用层次分析法确定各指标权重,结合中部地区农业、社会、经济和旅游等方面数据,对中部6省休闲农业可持续发展态势进行比较和分析,采用综合评价法,得出中部6省休闲农业可持续发展态势的综合排名。[结果]最终确定中部6省休闲农业可持续发展态势的综合评价指数,得到的河南省、山西省、湖北省、安徽省、湖南省和江西省的综合评价指数分别为0. 60、0. 24、0. 59、0. 43、0. 64、0. 46,并根据各省综合评价指数得出中部6省休闲农业可持续发展态势排名。其中,湖南省的休闲农业可持续发展态势最高,湖北省、河南省发展态势次之,江西省和安徽省休闲农业可持续发展态势较低,山西省休闲农业可持续发展态势最弱。[结论]中部地区休闲农业可持续发展态势差异明显,未来休闲农业可持续发展空间很大,中部地区发展休闲农业需要加强区域合作,发挥互补优势,提高旅游行业服务与管理水平,共建旅游发展大格局。     

Fashionability vis-à-vis rationality: investigating factors driving users’ e-tourism website stickiness

Understanding what drive users’ website stickiness is of strategic importance for e-tourism managers. This study examines the role of a neglected construct ‘perceived fashionability’ in forming users’ e-tourism website stickiness in comparison with four commonly studied rational factors: system quality, information quality, security and e-shopping value. Drawing upon dual-system theories and social influence theories, a conceptual model with hypotheses was developed and tested. A sample of 376 e-tourism website users in China participated in this study. The results indicate that perceived fashionability has a positive impact on user's stickiness to the website, and perceived fashionability also performs a mediating role between website security and stickiness. This study contributes to theory by explaining that website stickiness is not entirely driven by rationality but also perceived fashionability. Managerial implications for e-tourism strategies are provided.     

绍兴市土地利用时空变化研究

[目的]探讨经济发达地区土地利用变化时空规律,为城市发展提供合理土地利用政策,同时优化土地利用结构以支持经济可持续发展。[方法]通过遥感影像获取长时间序列的土地利用数据,探讨近30多年来绍兴市的土地利用变化,进一步利用土地利用动态变化模型,对绍兴市土地利用变化过程、趋势、变化轨迹进行了深入分析。[结果](1)绍兴市土地利用在1980~2000年相对稳定,在2000年后变化强度逐年增强,2005~2015年土地利用转化量增多和类型多样。绍兴市东北部平原和县区核心区域是经济发达地区土地利用变化的活跃区域,主要是其他类型土地向建设用地转移;(2)1980~2015年绍兴市土地利用变化轨迹主要受到人口增长和GDP增长的影响。[结论]城市化的发展和人口的迅速增长,使城市人口和土地面积迅速增加,造成城市边缘的农业用地转化成了建设用地。经济的发展、科技的进步及政府政策的制定,改变了人们的生活和工作方式,进而影响土地利用类型。     

Is China’s Manufacturing Industry Efficient? Evidence from an Energy-Rebound Effect Perspective

Majority of the increase in global energy consumption is from China; hence, studying energy issues, especially in China’s manufacturing industry (CMI), is worthwhile and of much interest in the academic field. Based on the translog cost function, we develop a research framework to study the rebound effect of CMI. Considering the effect of asymmetric energy price, we augment the energy-cost function with asymmetric influence constraint of energy price. Again, we add time series data of CMI’s capital, labor, energy, and mid-input to the model to calculate the direct rebound effect of CMI. We find that the rebound effect of CMI is 44.2%, and CMI still has large energy-conservation potentials. Based on the results of this study, some policy recommendations are provided.     

Longing for the past and embracing the new: Does nostalgia increase new product adoption?

Existing research has mostly focused on the salutary impact of nostalgia on nostalgia-related products (e.g., childhood products, classic brands). The current research examines whether this effect can extend to nostalgia-unrelated products: new products. We demonstrate that nostalgia fosters social support, which in turn encourages consumers to adopt new products, and this effect is weakened when individuals have independent self-construal. Three studies provide support for these predictions. Study 1 revealed that nostalgia increases new product adoption. Study 2 demonstrated that this positive effect of nostalgia on new product adoption is mediated by social support. Study 3 showed that this salutary effect occurs only when consumers’ interdependent self is activated. The marketing implications of these findings are discussed.
